2 women arrived and then a man from the past arrives with the means to claim and dispose of the corpse.
Parallels there with Amy, River and Canton perhaps?
Not sure where Rory fits in though
Wouldn't the 2 women and a man be Amy, River and Rory?
Yes but Rory wasn't a man from the past who arrived with the means to collect and dispose of the corpse - Canton was.
Rory is the Judas in the spacesuit that shoots him, maybe?
Rory the Roman?
М?
